A little more photo talk FYI - my students struggled with the answer to this question. How would you
or your students do?
QUESTION: If two lamps provide a level of illumination that produces two stop underexposure of a
given scene, how many ADDITIONAL lamps are needed to provide a level of illumination that will
result in a properly exposed scene?
1 2 3 4 6 8
circle one choice
To find out the answer (you can work out the reasons!) (or ask!) follow this link:

BTW, I have another hoky question for you: How wide is 35mm film?
